SPECIFICATION forming part of Letters Patent N0. 790,073, dated May 16,1905.

Application filed September 29, 1904. Serial No. 226,444.

To @ZZ whom it Hetty col/worn:Y

Be it known that I, JOHN MCMYLER, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented a certain new and useful lmprovement in Loading Machinery, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings.

This invention is an improvement in the means whereby loose materialsuch as coal, ore, or grain-may be conveyed Afrom an overhead platformor chute into the hold of a vessel and properly distributedthereinirrespective of the distance (within limits) between the chuteand the surface onto whichY the `material is to be delivered.

The invention has been contrived with special reference to use as partof av coal-cardumping machine; but it is not inherently limited to suchuse. v`

The invention .maybe summarized as consisting in the combinations ofparts hereinafter described, and definitely set forth in the claims.

In the drawings, Figure l is a plan view of the platform which supportsthe mechanism by which said moving parts are moved. Fig. 2 is a sideelevation of the one end of said platform, the lower end of the chute towhich it is attached, and the spout associated with said chute. Fig. 3is a front view of said spout, its support, and certain other mechanismhereinafter described.

Referring to the parts by letters, A represents an incline-chute ontowhich the material, such as coal, is to be delivered. rlhe Hoor-line ofthis chute is indicated by a, the

parts of the chute below said floor-line being the supporting-beams. Brepresents a telescopic discharge-spoutWthat is to say, a spout which iscomposed of several telescopingsections. The upper section I) is pivotedto some part of the structure of which said chute is a rigid part, thepivot being horizontal and the upper end of the spout being in suchposition that the material sliding down the chute will flow into theupper end of said spout. A platform C is rigidly fixed to the outer endof said chute and normally occupies a substantially horizontal position.On this platform are three rotatable shafts D, E, and N,

said shafts being mounted in suitable bearings and in parallelrelations. On theends of the two shafts D and E the sheaves (indicatedby CZ d' and e e', respectively) are secured. Loosely mounted on thesetwo shafts, respectively, are the two worm-wheels M M', and to the hubsm of each of these worm-.wheels one part, P, of a friction-clutch issecured. The other part, P', of said clutch is fixed to the associatedshaft. These clutches may be of any suitable or desired construction andmay be operated by a sliding sleeve P2'. A, motor-as, for example,engine Q-is secured upon the platform, and the motor-shaft Q' isprovided with two worms Q and Q', (shown in dotted lines in Fig. 1,)which engage, respectively, with the worm-wheels M M' and drive saidworm-wheels and shafts constantly while bles J are secured at one end tothe chute on opposite sides thereof and extend down under the twosheaves b3 and thence up to idlersheaves H and thence to the two sheavese e', respectively. rl`wo other cables, J', are secured to the platformC and pass down under the two sheaves 1 and thence up to the two sheavesZ d'.

It will be understood that the operator o f the mechanism hereindescribed is to stand upon the platform C and that the motor is inconstant operation. If now he desires to swing the spout bodily forwardor backward, he has only to throw in that friction-clutch P which willconnect either the shaft D or E, as required, to the associatedworm-wheel M or M', and the result will be the winding up of the propercables to cause said spout to swing in the desired direction, the cablesrunning in the other direction being free to unwind from their sheavesto permitthe Vspout to so swing. If it is desired to shorten the spoutwithout swinging it on its supporting pivot. both of the clutches P P'are thrown in and all of the cables J and J are wound up IOO i "Ivequally. The clutch-sleeves may be moved by any suitable mechanism; butin the embodiment of the inventionshown they are moved by the arms it',projecting from rockshafts K and having pins 71:', which enter thegrooves of the sleeves. These rock-shafts have also operating-arms 7a2,which are connected by suitable links k3 with other roekshafts 7a4,suitably mounted upon the platform, and all these and other rock-shaftsemployed in connection with other clutches to be specified are capableof being moved by Various levers L, respectively, grouped at someconvenient point.

0n the lower end of the spout B is what is sometimes called a trimmerthat is to say, it is a tubular section adapted to be swung into variouspositions relative to the spout, but in a direction transverse to thatdirection in which the spout swings as an entirety. There is nothing newin this swinging trimmer section-piece; but the mechanism by which itmay be swung as desired by the operator on the platform C is thought tobe new. rI he trimmer-section is supported by four substantiallyvertical links 2f t t' t', two of which are pivoted tothe front side andtwo to the rear side of said section. The upper ends of the two linksz5' t' on the rear side are pivotally connected with a rocker S, looselymounted on a stud S', which projects from the rear side of the lowerspout-section, the outer en d of this stud being supported by bracketsThe two linksziL t on the front side of said trimmer-section arepivotally connected at their upper ends with a rocker U; but this rockeris rigidly fixed to a rock-shaft U', on

`which is also secured a worm-segment U2.

A horizontal shaft Vis mounted on the front side of the lowerspout-section, and it carries a worm e, which engages with this segment.Two sheaves o' e2 are also secured to opposite ends of this shaft. Acable X, secured to and wound in one direction upon one of thesesheaves, extends up and is wound upon a sheave n upon the shaft N.Another cable, X', is wound in opposite direction upon the other sheaveand extends up to and is wound upon another sheave, n', on shaft N. Awormwheel M2, which engages a worm Q4 on the motor-shaft Q', is securedupon shaft N, and it and said shaft are constantly driven. There are twoclutches W W' on this shaft N, which are independently operable bysubstantially the same means which is provided and as hereinbeforedescribed for operating the other clutches, P. When one of theseclutches is thrown in, it connects one sheave, n, to the shaft and theassociated cable is wound up, thereby swinging this trimmer-section inone direction. When the other friction-clutch, W', is drawn in, thesheave n is connected with the shaft and the other cable is wound up andthe trimmer-section is caused to swing in the opposite direction. Thetwo sheaves om.'

on shaft N, on which these cables are wound, have also a frictionalconnection with the shaft, which frietional connection is suflicientlystrong to tend to rotate said shafts at all times. The tendency is notsufiieient to wind up the cables and thereby swing the trimmer-section,but is strong enough to keep the cables taut at all times. Thefrietioual connection between the sheaves and the shafts consist of apair of radially-movable shoes Y, which are supported by a disk 1/,secured to the shaft N, and these shoes are impelled outward intoengagement with a cylindrical fi an ge n2 on the sheaves by springs y'.

The combination of an inclined chute, a platform fixedthereto, and a telescopic discharge-spout suspended by a pivot from saidchute, two parallel shafts mounted upon vsaid platform each having asheave secured to each end, a rotatable shaft at right angles to saidtwo shafts carrying two worms, two wollnwheels loosely mountedrespectively upon the two parallel shafts, clutches for connecting saidworm-wheels to said shafts, and cables wound upon said sheaves andconnected with the lower section of the telescopic spout, andidler-sheaves over which two of said cables pass.
